somebody has broken gfortran

[Paul Thomas]

I was in the midst of doing a final regtest of the PR15809 patch, when 
all hell broke loose.  I reverted and the problem is still there:

[prt@localhost trunk]# svn status
?      gcc/testsuite/gfortran.dg/auto_char_dummy_array_1.f90      <<< ie 
the pr15809 testcase
[prt@localhost trunk]# svn up
At revision 107678.
[prt@localhost trunk]#

I cannot immediately see what the problem is either from the symptoms 
(seg faults) nor the ChangeLogs - I've had a bad day and am going to bed!
